probation and two years of suspension for each conviction (Item 1, Ex. 4). The two years of probation was unsupervised (Item 2, p. 3). Furthermore, he was neither fined nor sentenced to any term of imprisonment (Id.).
Section 173(l)(a) of the Canadian Criminal Code provides: “1) Every one who wilfully does an indecent act (a) in a public place in the presence of one or more persons, ... is guilty of an offence punishable on summary conviction.” Martin’S Annual Criminal Code (1983), attached at Item 4, p. 107
The Immigration and Naturalization Service (INS) conceded that the sexual assault conviction fell under the petty offense exception of the Immigration Act. Thus, only the indecent act conviction was relevant to the issue of whether petitioner was excludable pursuant to INA § 212(a)(2)(A)(i)(I), 8 U.S.C. § 1182(a)(2)(A)(i)(I), for a crime involving moral turpitude.
The immigration judge did not squarely address the issue of whether the petitioner’s crime involved moral turpitude. Rather, the immigration judge held that the Canadian statute proscribing the indecent act required a showing of “wilfulness,” or intent, and that the cases cited by the petitioner were inappo-site because the laws they construed did not require a showing of intent. Item 4, p. 67.
The immigration judge went on to observe that a Canadian court interpreting section 173 held: “In order for the act to be indecent, there must be moral turpitude to some degree.” Toutounjian, at Item 4, p. 66 (Citing Martin’S Annotated Criminal Code § 173 R. v. Springer (1975), 24 C.C.C.(2d) 56, 31 C.R.N.S. 48 (Sask.Dist.Dist.Ct.)). Consequently, the immigration judge held that this interpretation must be adopted, and petitioner’s crime found to be one of moral turpitude, “for to hold otherwise would entail disrespect for the judgments of another sovereign, and thus undermine the principle of international comity.” Toutounjian at Item 4, p. 67.
The Board of Immigration Appeals affirmed the decision of the immigration court without any discussion of moral turpitude. Item 4, p. 3.
DISCUSSION
I. Standard of Review
Final orders of exclusion of an alien may be reviewed only in a habeas corpus proceeding before the district court. Castillo-Magallon v. I.N.S., 729 F.2d 1227 (9th Cir.1984). A district court is not required to conduct a de novo hearing as part of its habeas corpus review of an exclusion order. De Brown v. Department of Justice, 18 F.3d 774 (9th Cir.1994). The Board of Immigration Appeal’s conclusions of law are reviewed de novo, but its factual findings are given considerable deference. Si v. Slattery, 864 F.Supp. 397 (S.D.N.Y.1994). It is well settled that a reviewing court may not reweigh the factors relevant to a discretionary determination by the BIA. I.N.S. v. Rios-Pineda, 471 U.S. 444, 452, 105 S.Ct. 2098, 2103, 85 L.Ed.2d 452 (1985).
However, when the BIA’s decision is fact-sensitive and failure to address relevant factors is of sufficient magnitude, the court may reconsider the merits of the decision. See Mejia-Carrillo v. United States Immigration and Naturalization Service, 656 F.2d 520, 522 (9th Cir.1981) (BIA’s decision may be reversed only for an abuse of discretion, such as failure to consider all relevant facts).
In discussing the standard of review of the decisions of an unrelated agency the Second Circuit Court of Appeals has held that an agency’s conclusions of law are reviewable under a higher standard than that of “abuse of discretion.” H.W. Wilson Co. v. United States Postal Service, 580 F.2d 33, 37 (2d Cir.1978). In H.W. Wilson, the Court of Appeals overturned the decision of the Postal Service that the petitioner’s publications were not periodicals. The court held that “when the question is one of law and does not implicate the expertise of the agency, we must provide a stricter standard of review. This is particularly true when, as in the present case, ‘the administrator’s legal decision is based on his interpretation of a judicial opinion that in turn construes a statute.” ’ Id.
